Awesome movie! If you haven't seen it, go ahead and watch it, it's definitely the movie of the year for me. But prepare, before and after all those cool action scenes you will have somthing to think about for sure.
With expressions like "totem" and "limbo" it seems a bit too superficial here and there but if you think about it: dreams are really weird, mysterious andthere is still no complete explanation what dreams exactly are or why do we dream afterall.
If you liked the Matrix probably you will enjoy Inception too cause they share some elements, but this movie is closer to real life, yet it's idea is way more complicated.
Let's hope the makers won't ruin the movie with future sequels.
